Teen star Miley Cyrus is fighting back over cruel criticism about her body shape, urging fans to be proud of their size and declaring, "I love myself!"

The former Hannah Montana star is tired of gossip bloggers speculating over her apparent weight gain after she was spotted with a more rounded figure in recent weeks.

The 18 year old has taken to her Twitter.com page to address the comments, posting a photo of an emaciated model and writing, "By calling girls like me fat, this is what you're doing to other people."

Cyrus also shared a snap of blonde bombshell Marilyn Monroe with the caption, "Proof that you can be adored by thousands of men even when your thighs touch."

She adds, "I love MYSELF & if you could say the same... I don't wanna be shaped like a girl I LOVE being shaped like a WOMAN & trust me ladies your man won't mind either."

Cyrus then reached out to her pal Demi Lovato, who checked into rehab last year (10) for an eating disorder among other issues, to celebrate her womanly shape, tweeting, "I will destroy any one that ever calls you the F (fat) word. You have the SEXIIIESTTTT curvyyyy body! I LOVE IT! Werk (work) those curves."
